RESPON PERTUMBUHAN DAN PRODUKSI TANAMAN SAWI HIJAU(Brassica juncea Linn.) DENGAN JENIS NUTRISI HASIL FERMENTASI MIKROBA DAN FERTILIZER TAMBAHAN PADA SISTEM HIDROPONIK SUBSTRAT

Abstract

This study aims to determine the response of the type of nutrient produced by microbial fermentation and the type of fertilizer addition on the growth of green mustard grown using the substrate hydroponic system. The research method used a randomized block design (RBD) arranged in a factorial. The first factor, is the type of nutrition from microbial fermentation, which consists of 4 levels, namely: N0: control; N1: nutrients fermented from tianfusc fungi, N2: nutrients fermented from bacteria G30N; and N3: nutrients from the fermentation of the G30Na bacteria. The second factor is additional fertilizer consisting of 3 levels, namely: a) P1: urea fertilizer with a concentration of 2 g / L; P2: micro fertilizer 1 concentration 100 ml / L; and P3: micro fertilizer 2 with a concentration of 100 ml / L, in order to obtain 12 treatment combinations that were repeated 4 times. The results showed that: a) the distribution of nutrients resulting from microbial fermentation and the type of fertilizer addition was significantly different in the observation variables for leaf area in the 1st, 2nd and 3rd observations as well as the total fresh weight and consumption weight at harvest time; b)The provision of types of nutrients resulting from fermentation and additional fertilizers did not show any interactions on the growth and yield of the mustard plant
